[Boost-users] [boost::iterators] Missing typedefs in v1.57

The typedefs for difference_type and reference used to be in scope for 
classes derived from iterator_facade.  Since v1.57 they have to be declared 
thus:

typedef typename iterator_facade_::difference_type    difference_type;
typedef typename iterator_facade_::reference        reference;

This seems out of place for a class that was designed to reduce boiler plate 
code.  However, if the change was intentional, please document it.

Thanks,
